Abstract
The utility model relates to a square hole ribbed support prestressed concrete composite slab, and belongs to the field of building structural shapes. According to the design, the square hole ribbed support prestressed concrete composite slab is composed of a prefabricated base plate and a cast-in-place concrete layer, the prefabricated base plate is composed of a reinforced concrete lower layer and a square hole ribbed support concrete upper layer, prestressed reinforcement is arranged on the reinforced concrete lower layer in the longitudinal direction of the prefabricated base plate, the square section hole ribbed support concrete upper layer is arranged on the surface of the reinforced concrete lower layer, square section foam concrete padding blocks are evenly arranged vertically and horizontally at intervals inside the square section hole ribbed support concrete upper layer, concrete longitudinal ribbed layers are longitudinally arranged at intervals along the square section foam concrete padding blocks, and longitudinal reinforcement holes and transverse reinforcement holes are arranged in the concrete longitudinal ribbed layers, so that the prefabricated base plate is formed. The concrete layer is arranged on the surface of the prefabricated base plate in a cast-in-place mode, namely an integral composite slab is formed, and according to the design, the composite slab is low in self weight, good in deformation resistance, capable of increasing the applicability of the transverse span and achieving industrialized production, convenient to produce and construct, and high in efficiency.
Description
Technical field
A kind of square opening rib of the utility model frame prestressed concrete overlapped slab, belongs to building structure section bar field.
Background technology
At present, the concrete floor in building field is divided into Bars In Poured Concrete Slab, precast plate and traditional superimposed sheet three types.Bars In Poured Concrete Slab globality and shock resistance are better, but construction is complicated and need to set up a large amount of templates, time-consuming taking a lot of work; Although precast plate does not need template, assembling speed is also very fast, and globality and the shock resistance of its structure are poor, and range of application is narrower; Though traditional superimposed sheet is developing aspect the combination of Bars In Poured Concrete Slab and precast plate to some extent, exists dead load larger, material expends many, and its pre-erection is unreliable with being connected of cast-in-place part.
Utility model content
The purpose of this utility model is to provide a kind of square opening rib frame prestressed concrete plate, alleviates floor deadweight, increases floor at weight capacity and the deformation resistance of horizontal span, to be applicable to the needs of long span building floor.Possess good insulation, soundproof effect simultaneously, and be suitable for the production of efficient industrial rate.
The utility model is realized by the following method:
A kind of square opening rib of the utility model frame prestressed concrete overlapped slab, by prefabricated panel and cast-in-situ concrete layer, formed, prefabricated panel is by steel concrete lower floor, square opening rib frame concrete upper strata forms, in steel concrete lower floor, along prefabricated panel, be vertically arranged with prestressed reinforcement, rib frame concrete upper strata, hole, square-section is arranged on steel concrete lower floor surface, in described rib frame concrete upper strata, hole, square-section, there is even spaced square-section foam concrete filling block in length and breadth, longitudinal separation along square-section foam concrete filling block is concrete longitudinal rib layer, in this concrete longitudinal rib layer, there are longitudinal reinforcement and transverse reinforcement hole, form prefabricated panel, at formed prefabricated panel surface cast-in-situ concrete layer, form one superimposed sheet.
Longitudinal two ends of described prefabricated panel are concrete enclosing end.
There is the contract of connection mouth longitudinal both sides of the edge of described prefabricated panel.
Described cast-in-situ concrete layer and prefabricated panel have concrete cross rib layer in the lateral separation of square-section foam concrete filling block, and this concrete cross rib layer has transverse reinforcement.
A kind of square opening rib of the utility model frame prestressed concrete overlapped slab superimposed sheet, in the square opening of prefabricated panel, settle foam concrete filling block, longitudinal separation along square foam concrete filling block is provided with reinforcing bar, has corresponding preformed hole through transverse reinforcement in this foam concrete filling block lateral separation, and its deadweight is little, anti-deformation is good, increased the applicability of its horizontal span, and, can batch production produce, production efficiency is high, and easy construction efficiency is high.

The specific embodiment
Now further illustrate by reference to the accompanying drawings implementation process of the present utility model.
The utility model superimposed sheet is comprised of prefabricated panel and cast-in-situ concrete layer, prefabricated panel is comprised of steel concrete lower floor 1 and square opening rib frame concrete upper strata 3, in described steel concrete lower floor 1, along plate parallel longitudinal interval, prestressed reinforcement 1-1 is set, prestressed reinforcement stretch-draw after-pouring certain thickness concrete, in Gai steel concrete lower floor 1, vertical, horizontal interval setting party's tee section foam concrete filling block 2, adopt current in the industry method that interior outer mold baffle plate is set, the longitudinal separation of square foam concrete filling block 2 arranges reinforcing bar J-1 and reserved transverse reinforcement hole 3-1, implement concreting longitudinal rib layer 3, the lateral separation 4-1 that retains square foam concrete filling block 2, form prefabricated panel, the longitudinal both sides of the edge of this prefabricated panel are provided with and connect contract mouth, its longitudinal two ends are concrete enclosing end, when prefabricated panel reaches after prescribed strength, be transported to job site assembling, and penetrate transverse reinforcement J-2 in the 3-1 of the transverse reinforcement hole of this prefabricated panel square-section foam concrete filling block, cast-in-situ concrete overlapping layers 5 on this prefabricated panel again, then at cast-in-situ concrete layer 5 and prefabricated panel, in the lateral separation 4-1 of square-section foam concrete filling block, form concrete cross rib layer 4, thereby form one superimposed sheet with prefabricated panel strong bonded.
